| 摘 要： | 核电站中所应用的给水加热器的建模是核电厂热力系统仿真的重要组成部分.文中建立了核电机组给水加热器双区多节点动态数学模型,并利用大亚湾核电站和秦山二期核电站中使用的高压给水加热器数据进行了稳态验证,仿真值与设计值相对误差在1%以内.在此基础上,利用所建模型研究了大亚湾核电站第6级给水加热器给水流量阶跃减少、加热蒸汽流量阶跃减少2种瞬态工况.结果表明,所建数学模型能够准确地反映给水加热器在特定工况下的动态特性,基本可以满足工程仿真分析的要求,并可作为工程仿真的一个模块使用.

| Abstract: | The modeling of a feed-water heater is an important part of the thermal system simulation in a nuclear power plant(NPP).In this paper,dual-zone and multi-node dynamic mathematical simulation model of the feed-water heater is built.This model is evaluated by comparing the design parameters of the Daya Bay NPP high-pressure feed water heaters and Qinshan Phase II NPP high-pressure feed water heaters.It is shown that the relative error between steady-state calculation result and design parameters is within 1%.... |
